Hot-air attachment for stoves



UNITED STATES PATENT OFFIC 'ISAAOBROOKE, OF POTTSTOWN, ASSIGNOR TO FLOYD, WELLS & 00., OF ROYERSFORD, PENNSYLVANIA.

HOT-AIR ATTACHMENT FOR STOVES SPECIFICATION forming part of Letters Patent No. 531,502, dated December 25, 1894. Application filed August 6, I894- Serial No. 519,527. (No model.)

- in the following specification and accompanyingdrawings. V My lnvention consists of an attachment to a stove, constructed to direct air'to the exterior of the cylinder or fire-pot, and then eject or discharge the same therefrom in heated conditionyas will be hereinafter set forth.

Figure 1 represents a central vertical section of a hot air attachment to a stove embodying my invention. Fig. 2 represents a horizontal section on line w, :r, Fig.1.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings: A designates a heating stove, which excepting the feature of my invention applied thereto is of usual construction.

Bdesignates the cylinder or fire-pot, and O the circumferential rim, in the present case constituting a deflector as will be hereinafter more fully explained.

D designates a jacket which incloses the fire-pot, and is separated therefrom, forming an air-receiving chamber E the lower portion of said jacket closing on the ash pit or base F, and the upper portion being separated from the rim 0; leaving the discharge passage G.

Projecting from the jacket D is a spout or nozzle H, which is open to the atmosphere and leads to the chamber E, whereby-air may be directed into the latter, said nozzle in the present case being at the rear of the stove.

. It will be seen that when air enters the chamber E, it is heated by contact with the exterior of the fire-pot, and escapes in hot condition through the passage G, and is defiected by the rim 0 into the apartment, it being evident that I provide a simple, inexpensive and convenient manner of producing an additional supply of hot air from a heating stove which may be of ordinary form and construction, and direct 'the'same from the stove, so as to be admirably adapted for warming feet but to this use I do not limt myself.

In order to prevent the heat from being expelled or discharged at the back of the stove or jacket, the upper end of the rear portion of the jacket is extended upwardly above the discharge passage G, forming the wall J which abuts against the under side of the rim or defiector C, and thus closes said passage at the rear, said wall being also extended to the sides of the fire-pot as at K, so that the hot air may be expelled in the main at the front of the fire-pot or stove.

The inner wall of the nozzle H isremoved, and the same is supplied by the wall of the ashpit or base F, thus simplifying, lightening and cheapening the construction of the attachment Having thus described my invention, what I'claim as new, and desire to secure by Letters Patent, is

combination with a jacket forming a chamber between the fire pot of'the stove, the lower portion of one side of the jacket being extended, forming with the wall of the ash pit of the stove, an air-supply nozzle, the remainder of the lower edge of the jacket be ing closed on the stove, and an outlet passage existing between said jacket and rim, said parts'being combined substantially as described.

ing closed at bottom, and having a discharge passage at top, a portion of the wall of said jacket extending above said passage and closing against the rim or deflector of the stove above said fire-pot, the parts being combined substantially as described.
